EXHAUST-STEAM SEPARATOR.

, Application. filed May 4,

My invention relates to improvements in exhaust steam separators for use in extracting or separating oil and water from exhaust steam, usually in advance of a condenser.l

rlhe object of the invention is to provide a separator in which all of the parts shall be fixed or stationary, which shall be of comparatively small size, weight and cost, and shall be dependably efficient. And further, to provide a device of this character which shall not be restricted t-o employment with exhaust steam but also adapted for use with other fluids. Other objects of the invention will appear hereinafter.

The structure embodying -the invention and the means employed in the attainment of the foregoing objects will be clearly understood on reference to the drawings that foi-in part of this specification; and in which Fig. 1 is a vertical section of a. separator embodying my invention; Fig. 2 is a like section on the line 2 2 of Fig. 1; Fig. 3 is a horizontal section on the line 3 3 of Fig.

1; and Fig. 4 is a horizontal section on the line 4-4 of Fig. 2.

The fixture of this invention stands upright, the fluid entering at the top opening A and leaving at the bottom outlet B. It is of extremely simple construction, comprising only four parts; namely, the base C, the higher top D, the fluid-whirling member E, and side plate F. On the removal of the latter the fiiiid-whirliiig member may be easily taken out. inspected, or cleaned, and replaced.

The bowl-like base C has a base flange 2 and contains the central stand-pipe 3. The top of the latter contains the initial outlet 4 of the separator, and is encircled by the beveled flange 5. The top of the member C is marked by the bolt flange 6, positioned below the top of the stand-pipe 3. The arrangement shown provides the annular collection cavity or pocket G within the baser C; and, for emptying this pocket a tangential discharge nozzle G is provided at the bottom thereof. The direction of the outlet corresponds to the whirl of the fluid which is set in rotation by the action of the member E.

The bottom of the part D has a flange 7 which is secured on the flange 6 by bolts 8. The internal horizontal rib 9 divides the member D into a lower cavitv D2 (which is 1925. Serial No. 27,862.

an upward extension of the pocket G) and a tall cavity D. The lower cavity D2 encloses the flanged top of the standpipe 3 and its walls are spaced therefrom to form the circumferential race or cavity H and the annular opening G.

The rib 9 contains the central hole 10 which is somewhat larger than the outlet 4. On the top of the rib is a U-shaped shoulder 11 which receives the base of the fluid-whirling member E. vTwo lugs 12 overlap the sides of the shoulder 11 and serve to hold the member E thereon. As will be apparent the sides of the shoulder 11 serve to center the member E over the hole 10 and the outlet 4.

The side of the casing member D contains a rectangular opening extending upward from the floor or shoulder 11, large-enough to freely admit the member E and framed to receive the plate F. The upper end of the member D is coned or cont-racted and is marked by a top flange 13.

The side plate F is secured by'a number of bolts 14 and is distinguished by an inwardly projecting lug F at the level of the shoulder 11. The inner end of the lug F engages the base of the member E and completes the holding of the latter on the shoulder 11.

'lhe member E is generally cylindrical being composed of the bottom ring 15 `and the circumferential series of operatively overlapping tangential blades 16, that rise therefi'oiii. narrow'tuyres E and constitute a. taiigential tuyere ring or barrel which is coaxial with the openings 4 and 10. The upper end of the ring or barrel is closed by the cap 17. The latter is carefully distinguished by the .circumferential shoulders 18 and'19 which provide the under side of the cap with a peripheral collecting groove 20. The cap may be solid or may contain the central cavity 21. The work of separation is done at the periphery and the shape of the central portion of the cap is relatively unimportant.

it is to be noted that the tuyeres E are very narrow, but are of such number and Vof such lengths that the aggregate tuyre area or capacity of the member E greatly exceeds the area of the outlet 4. Thereby, substantially the same pressures are ensured at the inlet A and the outlet B.

Exhaust steam, or the like, entering the These blades form the many inlet A at the top of the separator and at high velocity, occupies the larger cavity D and is distributed to the many tuyres E. On entering the tangential tuyres the thin streams of steam immediately impact the in-V ner sides of successive blades and thus the heavier substances are instantly deposited thereon. The tangential entrance of the many streams results in the very rapid ro'- tation of the fluid within the member E and the circumferential gap H and to some eX- tent in the cavity G. The peripherally collected substances are driven to the bottom of the tuyere ring or barrel by the longitudinal flow of the whirling-fluid and on reaching the opening 10 are centrifugally ejected into the gap H and fall therefrom into the cavity G. Meantime, the purified liuid whirls away through the outlet li at the top of the stand-pipe 3. rlhe accumulating substances in the bottom of the cavity G are drained away through the outlet G', an automatic discharge trap being preferably connected therewith.

Then the plate F is removed the member E may be slipped .in or out on the flat floor or shoulder ll. t-te-ntion is called to the fact that a tight joint is not required between the rib 9 and the base of the member E.

Having thus described my invention I claim as new and desire to secure by Letters Patent:

l. The improvement herein described comprising the vertical casing having an inlet at the top and an outlet at the bottom, in combination with a stand-pipe rising within the lower part of said casing, a horizontal annular rib extending inwardly from the wall of the casing, about said stand-pipe and containing a central opening larger than that in the stand-pipe, a fluid-whirling member occuping the. upper part of said casing and resting on said rib, said casing having in its side above said rib an opening larger than said fluid whirling member and normally closed by a cover plate, and said member being laterally withdrawable from the casing through said opening when the cover plate is removed.

2. The improvement herein described comprising the vertical casing having an inlet at the top and an outlet at the bottom, in combination with a stand-pipe rising within the lower part of said casing, a horizontal rib extending inwardly from the wall of the casing, above said standpipe, and containing a central opening larger than that in said stand-pipe, a fluid-whirling member occupying the upper part of said casing and resting on said rib, the top of said rib being formed as a slide for said'member, said casing having an opening in its side for the rcception and removal of said member, and a plate covering said opening.

3. The improved separator herein de scribed, comprising a casing having an inlet at the top and an outlet at the bottom, and provided with an intermediate internal transverse circumferential rib, the latter containing an opening larger than said outlet, in combination with a barrel-lile multiple tangential tuyre ring slidably positioned on said rib and having a suitable end closure adjacent said inlet, said easing having an opening in its side to permit the sliding out of said tuyere ring, and a cover plate normally closing such side opening.

4l. The improved separator herein described, comprising a casing having an inlet at the top and an outlet at the bottom, and provided with an intermediate internal transverse circumferential rib, the latter containing an opening larger than said outlet, in combination with a barrel-like multiple tangential tuyre ring slidably positioned on said rib and having a suit-able end closure adjacent said inlet, said casing having an opening in its side to permit the sliding out of said tuyre ring, a cover plate normally closing such side opening, and means upon said 'cover plate normally serving to look said tuyre ring in place on said rib.

5. The improved separator herein de scribed comprising a vertical casing having an inlet in its top and in its lower part containing a stand-pipe and an encompassing collection space, said stand-pipe forming the outlet of the separator and at its top provided with a laterally extending integral flange of less diameter than said casing, and a whirl promoting member having a central discharge coaxial with said stand-pipe and fixed in said casing above said stand-pipe, and said central-discharge and vstand-pipe being in free radial and axial communica tion.

In testimony whereofl I have hereunto set my hand this 30th day of April A. D. 1925.
